第4周--计算机硬件常用术语(1).doc

计算机英语教案4训练课题：_计算机硬件常用术语（1）_ 第_4_周理论分析 计算机硬件是首先应该掌握的，课本中第一节内容就为计算机硬件常用术语。但是在所有罗列出的160多个术语中，并不是所有的术语都是常用的，所以在这一周内，主要学习第1、2页的常用内容，其它的单词让学生了解即可。训练目标知识与技能：记忆计算机硬件常用术语（1）。因为缩写内容较多，是本节的难点，应该多强调让学生主动记忆。过程与方法：在以后的学习过程能灵活应用这些英语。情感、态度、价值观：培养学生自学能力。 训练过程（以项目式或任务式为主） 项目设计：一请问在课本第一节的内容，你们认识的英文单词有哪些？二补充学生不会的单词，以下为学习的全部内容：A computer is a programmable machine with two principal characteristics. Firstly, it responds to a specific set of instructions in a well-defined manner. Secondly, it can execute a prerecorded list of instructions, which is referred to as a program. Modern computers are electronic and digital. The actual machinery, including wires, transistors, and integrated circuits, is called hardware; and the instructions and data are called software.All general-purpose computers require the following hardware components; Memory, which enables a computer to store, at least temporarily, data and program. Mass storage device, which allows a computer to permanently retain large amounts of data, including disk drives, tape drives, and laser discs. Input device, which, in the form of a keyboard and a mouse, is the conduit(channel)through which data and instructions enter a computer. Output device, which covers such equipment as the display screen, the printer, and various other devices through which you can see what the computer has accomplished. CPU, which stands as the heart, or, you may just as well say, the brain of the computer, carrying out instructions provided either by the user or the system itself.In addition to these components, many others make it possible for the basic components to work together efficiently. For example, every computer requires a bus that transmits data from one part of the computer another. Common bus types include ISA, PCI, VESA, and a few others.【新单词】New Wordsinstruction instrkn指令componentkmpunnt 组件memorymemri存储器，内存displaydisplei显示，显示器digitaldiditl数字的keyboardki:b:d键盘printerprint打印机devicedivais设备inputinput输入formf:m表格mousemaus鼠标outputautput输出busbs总线 carry out 执行 项目实施：1老师提问，学生回答。2 罗列内容，领读记忆。3学生引读，熟悉内容。4 布置作业，巩固知识。 项目应用：在实际见到相应的硬件应该知道其英文名称，如果出现的是英文名称，则应该其中文名称。 项目效果：因为硬件术语学生知道的较多，所以在记忆时，学生积极主动
